[0058] When a powder coating is formed on the surface of a workpiece using a powder coating device, the thickness uniformity of the powder coating on the surface of the workpiece is poor, which affects the performance of the part.

[0059] In order to solve the above technical problems, an embodiment of the present application provides a powder coating device, which comprises a regulating structure arranged between the air delivery structure and the powder barrel, wherein the regulating structure has a regulating chamber, the regulating chamber has at least one air inlet and multiple air outlets, the regulating chamber is connected to the air delivery structure through the air inlet, and the regulating chamber is connected to the accommodating chamber through the multiple air outlets.

[0060] When a powder coating is formed on the surface of a workpiece by using a powder coating device, an air delivery structure can be used to output an air flow toward the accommodating cavity of the powder cartridge through the regulating structure. The air delivery structure can output an air flow toward the regulating cavity through an air inlet, so that the air flow can flow to the accommodating cavity through a plurality of air outlets in the regulating cavity, so that the air flow discharged from the plurality of air outlets can drive the powder in the powder cartridge to be coated on the workpiece;

[0061] Compared with the method in the related art that the gas delivery structure is directly connected to the accommodating chamber, the embodiment of the present application sets an adjustment structure to enable the gas delivery structure to output airflow through multiple air outlets of the adjustment structure, so that the airflow of the multiple air outlets can drive the powder at different positions in the powder barrel to be coated on the surface of the workpiece, thereby making the powder coating thickness on the surface of the workpiece more uniform and improving the performance of the parts.

[0062] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0063] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0064] Reference Figure 1 and Figure 2 , please provide a powder coating device according to an embodiment, including a powder cartridge 100, a gas delivery structure 300 and an adjustment structure 200. The powder cartridge 100 may have a receiving cavity 110, in which powder may be contained and a workpiece to be processed may be placed, so that a powder coating may be formed on the surface of the workpiece using the powder in the receiving cavity 110.

[0065] Exemplarily, the gas delivery structure 300 can be disposed at the bottom of the powder cartridge 100. The gas delivery structure 300 can be connected to the powder cartridge 100 through the adjustment structure 200, and the gas delivery structure 300 can output airflow to the accommodating chamber 110 of the powder cartridge 100 through the adjustment structure 200, thereby driving the powder in the accommodating chamber 110 to be coated on the surface of the workpiece to form a powder coating.

[0066] Reference Figure 2 and Figure 3 The regulating structure 200 may be disposed on the powder cartridge 100, and the regulating structure 200 may include at least one regulating chamber 240. The regulating chamber 240 may have at least one air inlet 241 and a plurality of air outlets 242. The regulating chamber 240 may be connected to the air delivery structure 300 through the air inlet 241, and the regulating chamber 240 may be connected to the accommodating chamber 110 through the plurality of air outlets 242.

[0067] Multiple air outlets 242 can be evenly distributed at the bottom of the accommodating cavity 110, so that the multiple air outlets 242 can be used to drive the powder in the accommodating cavity 110 to be coated on the surface of the workpiece. The airflow discharged by the multiple air outlets 242 can drive the powder at different positions in the powder barrel 100 to be coated on the surface of the workpiece, thereby making the powder coating thickness on the surface of the workpiece more uniform.

[0068] Reference Figure 4 The powder coating device may further include a vibration structure 500. The vibration structure 500 may be provided with a bearing surface, and the bearing surface may be used to connect at least one of the powder cartridge 100, the adjustment structure 200 and the gas delivery structure 300.

[0069] By adopting the above technical solution, a vibration structure 500 is provided, and the bearing surface of the vibration structure 500 is connected to at least one of the powder barrel 100, the adjustment structure 200 and the gas delivery structure 300, so that the vibration structure 500 is used to drive the powder in the powder barrel 100 to vibrate, so that the powder in the powder barrel 100 can be evenly distributed, and the powder thickness at different positions in the powder barrel 100 is more uniform, so that the thickness of the powder coating on the surface of the workpiece can be more uniform through the cooperation between the vibration structure 500 and the adjustment structure 200.

[0070] Reference Figure 2 and Figure 3 In some possible implementations, the powder cartridge 100 may extend along a first direction, and the powder cartridge 100 and the adjustment structure 200 may be arranged in sequence along the first direction, wherein the powder cartridge 100 may be located above the adjustment structure 200. The first direction may be set as a vertical direction, or the first direction may also be set as an inclined direction.

[0071] Taking the plane perpendicular to the first direction as the cross section, the cross-sectional shape of the powder cartridge 100 can be set to be square, or the cross-sectional shape of the powder cartridge 100 can also be set to be circular. In the first direction, the cross-sectional area of ​​the powder cartridge 100 can be set uniformly, or the cross-sectional area of ​​the powder cartridge 100 can also gradually decrease in the direction away from the adjustment structure 200, and the embodiment of the present application does not impose further restrictions on this.

[0072] The inner wall of the powder cartridge 100 can be surrounded to form a receiving chamber 110, and the bottom wall of the receiving chamber 110 of the powder cartridge 100 can be arranged in the horizontal direction. The bottom wall of the receiving chamber 110 of the powder cartridge 100 can form a plurality of air outlets 242, and the plurality of air outlets 242 can be evenly arranged in the horizontal direction, so that the powder at different positions of the bottom wall of the receiving chamber 110 of the powder cartridge 100 can be driven to be coated on the surface of the workpiece through the plurality of air outlets 242.

[0073] Reference Figure 2 and Figure 3In some possible implementations, the adjustment structure 200 includes a main body 210 and a barrier assembly. The main body 210 extends along a first direction. The shape of the main body 210 can be the same as that of the powder cartridge 100, and the main body 210 can be coaxially arranged with the powder cartridge 100.

[0074] Taking the plane perpendicular to the first direction as the cross section, the cross-sectional shape of the main body 210 can be set to a square, or the cross-sectional shape of the main body 210 can also be set to a circle. In the first direction, the cross-sectional area of ​​the main body 210 can be set uniformly, or the cross-sectional area of ​​the main body 210 can also gradually decrease in the direction away from the gas delivery structure 300, and the embodiment of the present application does not impose further restrictions on this.

[0075] Exemplarily, the main body 210 and the partition assembly can be jointly arranged to form an adjustment chamber 240 .

[0076] The barrier assembly may include a first mounting plate 220 and a second mounting plate 230. The first mounting plate 220 may be disposed at the first end of the main body 210, and the first mounting plate 220 may block the opening of the main body 210 toward the powder cartridge 100. The first mounting plate 220 may be provided with a plurality of air outlets 242, so that the regulating chamber 240 can be connected to the accommodating chamber 110 of the powder cartridge 100 through the plurality of air outlets 242 located on the first mounting plate 220.

[0077] The first mounting plate 220 and a portion of the inner wall of the powder cartridge 100 may form a receiving chamber 110 , so that the structure of the powder cartridge 100 is simpler and the functions of the first mounting plate 220 are more abundant.

[0078] Exemplarily, the second mounting plate 230 can be disposed at the second end of the main body 210, and the second mounting plate 230 and the first mounting plate 220 can be disposed parallel to each other along a first direction. The second mounting plate 230 is provided with an air inlet 241 so that the gas delivery structure 300 can output airflow toward the regulating chamber 240 through the air inlet 241 located on the second mounting plate 230.

[0079] Reference Figure 2 and Figure 3 In the first mounting plate 220, the number of the air outlets 242 is set to be multiple, and the multiple air outlets 242 can be arranged in multiple rows and columns. In the second mounting plate 230, the number of the air inlets 241 can also be set to be multiple. The multiple air inlets 241 and the multiple air outlets 242 can be set one by one, and the corresponding air inlets 241 and air outlets 242 can be arranged in the vertical direction.

[0080] A plurality of air outlets 242 are evenly distributed at the bottom of the powder cartridge 100. The air outlets 242 are used to intercept powder from entering the regulating chamber 240. It is easy to understand that the diameter of the air outlets 242 can be smaller than the particle size of the powder, so that the powder can be intercepted by the air outlets 242, reducing the possibility of the powder in the accommodating chamber 110 falling into the regulating chamber 240.

[0081] It is easy to understand that when a powder coating is formed on the surface of a workpiece using a powder coating device, the air supply structure 300 can be used to output airflow toward the regulating chamber 240 through the air inlet 241 located on the second mounting plate 230, so that the airflow can be output from the regulating chamber 240 toward the accommodating chamber 110 through the multiple air outlets 242 located on the first mounting plate 220, so that the airflow discharged from the multiple air outlets 242 can be used to drive the powder at different positions in the powder barrel 100 to be coated on the surface of the workpiece, so that the thickness of the powder coating on the surface of the workpiece is more uniform.

[0082] Reference Figure 2 and Figure 3 In some possible implementations, the powder cartridge 100 may be provided with a mounting flange 120. The main body 210 may be provided with a first mounting portion 211, and the first mounting portion 211 is attached to the mounting flange 120. The first mounting portion 211 may be used in conjunction with the mounting flange 120 to relatively fix the powder cartridge 100 and the adjustment structure 200.

[0083] The first mounting plate 220 may be provided with a first sealing member 221. The first sealing member 221 may be sleeved outside the first mounting plate 220. In the first direction, a first surface of the first sealing member 221 may be attached to the powder cartridge 100, and a second surface of the first sealing member 221 may be attached to the main body 210.

[0084] Between the mounting flange 120 and the first mounting portion 211, the mounting flange 120 can be in contact with the first surface of the first sealing member 221; the first mounting portion 211 can be in contact with the second surface of the first sealing member 221, so that the first sealing member 221 can fill the space between the first mounting portion 211 and the mounting flange 120, thereby reducing the possibility of a gap between the first mounting portion 211 and the mounting flange 120.

[0085] Exemplarily, the powder cartridge 100 may also be provided with a first connecting member 222. The first connecting member 222 fixes the mounting flange 120, the first sealing member 221 and the first mounting portion 211, so that the connection between the powder cartridge 100 and the adjustment structure 200 is realized through the first connecting member 222, so that the first connecting member 222 can cooperate with the first sealing member 221, thereby making the connection between the mounting flange 120, the first sealing member 221 and the first mounting portion 211 more stable.

[0086] The first connection member 222 may surround the outer side of the first sealing member 221. The first connection member 222 may be provided with a first fixing groove 2221, and the first fixing groove 2221 is used to accommodate the mounting flange 120, the first sealing member 221 and the first mounting portion 211, so that the first fixing groove 2221 plays a certain role in limiting the mounting flange 120, the first sealing member 221 and the first mounting portion 211.

[0087] The first connecting member 222 may include a first end and a second end disposed along the circumference of the first sealing member 221 . The first end of the first connecting member 222 and the second end of the first connecting member 222 may be movably connected to achieve connection between the powder cartridge 100 and the adjustment structure 200 through the first connecting member 222 .

[0088] Reference Figure 2 , Figure 3 and Figure 5 A fixing assembly 400 may be provided between the first end and the second end of the first connecting member 222. The fixing assembly 400 may include a clamping member 410 and a clamping rod 420, one of which is mounted on the first end of the first connecting member 222, and the other of which is mounted on the second end of the first connecting member 222.

[0089] The clamping member 410 may be provided with a clamping groove 411, and the clamping groove 411 may face the clamping rod 420. When the first connecting member 222 is used to fix the mounting flange 120, the first sealing member 221 and the first mounting portion 211, the first connecting member 222 may surround the outer side of the first sealing member 221, and the first fixing groove 2221 accommodates the mounting flange 120, the first sealing member 221 and the first mounting portion 211;

[0090] Then, the first end and the second end of the first connecting member 222 are brought close to each other, and then the clamping rod 420 is rotated so that the clamping rod 420 can be inserted into the clamping groove 411 of the clamping member 410, so that the first end and the second end of the first connecting member 222 are fixed by the cooperation of the clamping rod 420 and the clamping member 410, and then the powder cartridge 100 and the adjustment structure 200 can be fixed by the first connecting member 222.

[0091] It is easy to understand that the fixing assembly 400 can also be configured as other connection modes. For example, the fixing assembly 400 can also be configured as matching fixing bolts and fixing nuts.

[0092] Among them, the fixing bolt can be passed through the first end and the second end of the first connecting member 222, and the fixing nut is threadedly connected to the fixing bolt, so that the first end and the second end of the first connecting member 222 can be fixed by matching the fixing bolt and the fixing nut.

[0093] Reference Figure 2 , Figure 3 and Figure 6 Exemplarily, the adjustment structure 200 may further include a first support member 243. The first support member 243 may be disposed in the adjustment cavity 240, a first end of the first support member 243 along the first direction may be connected to the second mounting plate 230, and a second end of the first support member along the first direction may be connected to the first mounting plate 220.

[0094] In this way, the first support member 243 supports and protects the first mounting plate 220 and the second mounting plate 230 which are arranged in parallel and opposite to each other, thereby reducing the possibility that the first mounting plate 220 is bent and deformed by the gravity of the powder.

[0095] Reference Figure 2 , Figure 3 and Figure 5 For example, the gas delivery structure 300 may be provided with a fixing flange 320. The main body 210 may be provided with a second mounting portion 212, and the second mounting portion 212 is attached to the fixing flange 320. The second mounting portion 212 may be used in conjunction with the fixing flange 320 to relatively fix the gas delivery structure 300 and the adjustment structure 200.

[0096] The second mounting plate 230 may be provided with a second sealing member 231. The second sealing member 231 may be sleeved outside the second mounting plate 230. In the first direction, the second surface of the second sealing member 231 may be attached to the gas delivery structure 300, and the first surface of the second sealing member 231 may be attached to the main body 210.

[0097] Between the fixing flange 320 and the second mounting portion 212, the fixing flange 320 can be fitted to the second surface of the second sealing member 231; the second mounting portion 212 can be fitted to the first surface of the second sealing member 231, so that the second sealing member 231 can fill the space between the second mounting portion 212 and the fixing flange 320, thereby reducing the possibility of a gap between the second mounting portion 212 and the fixing flange 320.

[0098] Exemplarily, the gas delivery structure 300 may also be provided with a second connecting member 232. The second connecting member 232 connects the fixing flange 320, the second sealing member 231 and the second mounting portion 212, so that the gas delivery structure 300 and the adjustment structure 200 are connected through the second connecting member 232, so that the second connecting member 232 can cooperate with the second sealing member 231, thereby making the connection between the fixing flange 320, the second sealing member 231 and the second mounting portion 212 more stable.

[0099] The second connecting member 232 may surround the outer side of the second sealing member 231. The second connecting member 232 may be provided with a second fixing groove 2321, and the second fixing groove 2321 is used to accommodate the fixing flange 320, the second sealing member 231 and the second mounting portion 212, so that the fixing flange 320, the second sealing member 231 and the second mounting portion 212 are limited to a certain extent by the second fixing groove 2321.

[0100] The second connecting member 232 may include a first end and a second end arranged along the circumference of the second sealing member 231 , and the first end of the second connecting member 232 and the second end of the second connecting member 232 may be movably connected to realize the connection between the gas delivery structure 300 and the adjustment structure 200 through the second connecting member 232 .
